Ten years of rapid development in chemical engineering technology – praising the prosperity and strength of modern China. This is just a starting point to encourage more people to participate and bring more enthusiasm to the discussion. With you here, HaiChuan becomes even better. [Ten years of development in chemical engineering equipment] – continuous updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhancing quality awareness to promote high-quality development. ----------------------------------------- Metallocene polyethylene boasts advantages such as good transparency, high heat-sealing strength, excellent tensile and impact resistance, as well as strong puncture resistance, which make it highly favored by downstream manufacturers and it is a sought-after product among high-end polyolefin products. For a long time, metallocene polyethylene products in our country have relied mainly on imports from abroad. In recent years, CNPC has attached great importance to the research and development of metallocene polyolefin products. The product developed by Guangdong Petrochemical is a metallocene-based high-performance film material, which is widely used in areas such as resealable packaging films, food packaging, various types of flexible packaging, stretch-wrapping films, and medical and health applications. At 10:40 on September 9, the successful production of HPR-3518CB metallocene polyethylene by Guangdong Petrochemical Company’s 800,000 tons per year full-density polyethylene plant marked a significant technical breakthrough for this facility, following the successful steady production of products using titanium-based and chromium-based catalysts. To ensure the smooth progress of product development, Guangdong Petrochemical established a dedicated task force for the development of new metallocene polyethylene products. This team coordinated efforts in various areas such as raw material preparation, assessment of plant operation status, production technology plans, laboratory analysis, staff training, and integration of production with sales, putting in significant effort into the development of these metallocene products. During the final stage of production preparation, Guangdong Petrochemical Company overcame the adverse effects of the rainy weather during the typhoon season, and carried out a 5-day minor repair on the full-density polyethylene plant starting from September 3, clearing the way for the commissioning of the metallocene-based products. Guangdong Petrochemical’s full-density polyethylene plant was put into operation for the first time in mid-February this year. The successful development of these metallocene polyethylene products has added new members to the series of products produced by this facility. Currently, the products include titanium-based film materials, injection-molded plastics, chromium-based film materials, small and medium-sized hollow products, and metallocene-based film materials. As of August 31, 220,000 tons and 127,000 tons of titanium-based and chromium-based products had been produced respectively.
